CAS No. 13730-98-8 Application:
As plant growth regulator, it can be absorbed by plant via root, stem, leaf, bloom
1. 4-Chlorophenoxyacetic acid ( 4-CPA ) CAS No. 13730-98-8 is used to prevent abscission of bloom and fruit, inhibit rooting of beans, promote fruit set, induce formation of seedless fruit, through flower spraying.
2. 4-Chlorophenoxyacetic acid ( 4-CPA )performs better when used in combination with 0.1% monopotassium phosphate.
3.4-Chlorophenoxyacetic acid ( 4-CPA ) can be used for ripening and fruit thinning.
4. 4-Chlorophenoxyacetic acid ( 4-CPA ) also has herbicidal effect at high dosage
